Represents a section of a Configuration

  • Method Details

    • getKeys

      @NotNull Set<String> getKeys​(boolean deep)
      Gets a set containing all keys in this section.

      If deep is set to true, then this will contain all the keys within any child ConfigurationSections (and their children, etc). These will be in a valid path notation for you to use.

      If deep is set to false, then this will contain only the keys of any direct children, and not their own children.

      Parameters:
      deep - Whether or not to get a deep list, as opposed to a shallow list.
      Returns:
      Set of keys contained within this ConfigurationSection.

    • getValues

      @NotNull Map<String,​Object> getValues​(boolean deep)
      Gets a Map containing all keys and their values for this section.

      If deep is set to true, then this will contain all the keys and values within any child ConfigurationSections (and their children, etc). These keys will be in a valid path notation for you to use.

      If deep is set to false, then this will contain only the keys and values of any direct children, and not their own children.

      Parameters:
      deep - Whether or not to get a deep list, as opposed to a shallow list.
      Returns:
      Map of keys and values of this section.

    • contains

      boolean contains​(@NotNull String path)
      Checks if this ConfigurationSection contains the given path.

      If the value for the requested path does not exist but a default value has been specified, this will return true.

      Parameters:
      path - Path to check for existence.
      Returns:
      True if this section contains the requested path, either via default or being set.
      Throws:
      IllegalArgumentException - Thrown when path is null.

    • contains

      boolean contains​(@NotNull String path, boolean ignoreDefault)
      Checks if this ConfigurationSection contains the given path.

      If the value for the requested path does not exist, the boolean parameter of true has been specified, a default value for the path exists, this will return true.

      If a boolean parameter of false has been specified, true will only be returned if there is a set value for the specified path.

      Parameters:
      path - Path to check for existence.
      ignoreDefault - Whether or not to ignore if a default value for the specified path exists.
      Returns:
      True if this section contains the requested path, or if a default value exist and the boolean parameter for this method is true.
      Throws:
      IllegalArgumentException - Thrown when path is null.

    • isSet

      boolean isSet​(@NotNull String path)
      Checks if this ConfigurationSection has a value set for the given path.

      If the value for the requested path does not exist but a default value has been specified, this will still return false.

      Parameters:
      path - Path to check for existence.
      Returns:
      True if this section contains the requested path, regardless of having a default.
